PARKER阀TDA系列介绍
TDA 系列 2 通比例节流阀用于控制大流量油。
特点
• 腔体和安装模式符合 DIN ISO 7368。
• 断电时具有故障保存功能。
• 端口 B —> A 无泄漏。
• 允许压差高达 350 bar。
• 流量 A —> B 可选。
功能
比例流量阀设计为三级。阀芯由带阀座结构的顺序阀芯先导操作。带有力反馈的磁性、无级可调、可调阀控制顺序阀芯的位置。因此，阀芯的位置不受压差影响。压差可达到最大工作压力。先导体积要求约为 1 l/min。操作的最小压力为 3 bar。
先导压力必须大于连接 A 中的系统压力的 25%。流量调节精度为 0.5%。由于渐进特性流线，在低流量时，该值在渐进区内可提高 0.25%。零行程调节时间约为 25 毫秒。阀门流动方向为从 B 到 A。在关闭的中性位置，阀门从 B 到 A 无泄漏。在此中性位置，先导阀不需要任何先导油。油箱连接 Y 的压力不得高于 100 bar。
The 2-way proportional throttle valves of the TDA series are used to control large oil flows.
Features
• Cavity and mounting pattern according to DIN ISO 7368.
• Fail save function at power failure.
• Leak-free from port B —> A.
• Pressure difference up to 350 bar allowed.
• Flow A —> B optional.
Function
Proportional flow valves are designed with three stages. The valve poppet is pilot-operated by a sequence spool with seat construction. A magnetic, infinitely variable, adjustable valve with force feedback controls the position of the sequence spool. Thus the position of the poppet cannot be affected by differential pressure. The differential pressure can be up to the maximum working pressure. The Pilot volume requirement amounts to approx. 1 l/min. The minimum pressure for operation is 3 bar.
The pilot pressure must be larger than 25% of the System pressure in connection A. The adjusting accuracy of the flow is 0.5%. Due to the progressive characteristic flow line, this value is improved by 0.25% in the progressive zone at low flow rates. The adjusting time for null stroke is approx. 25 ms. The valve flow direction is from B to A. The Valve is leak-free from B to A in the closed neutral position. In this neutral position, the pilot valve does not require any pilot oil. The tank connection Y must not be pressurised higher than 100 bar.
